They have 6mm threads and are screwed into the valve cover. If you look closely you will see 2 little tabs that lock them into place. You can break the tabs and unscrew them or just break them, get the pieces out of the valve cover and just use regular 6mm bolts or screws to fasten the cover back on. (as I did on my car)
